Where Are My Pants?

The Wall Street Journal reports today that Walmart is progressing in its efforts to incorporate RFID (radio-frequency identification) devices into its inventory. The technology, which allows for monitoring of individual items within a supply chain, is state of the art, but comes with some privacy concerns.

Starting next month, the retailer will place removable "smart tags" on individual garments that can be read by a hand-held scanner. Wal-Mart workers will be able to quickly learn, for instance, which size of Wrangler jeans is missing, with the aim of ensuring shelves are optimally stocked and inventory tightly watched. If successful, the radio-frequency ID tags will be rolled out on other products at Wal-Mart's more than 3,750 U.S. stores...

Robert Carpenter, chief executive of GS1 U.S., a nonprofit group that helped develop universal product-code standards four decades ago and is now doing the same for electronic product codes, said the sensors have dropped to as little as seven to 10 cents from 50 cents just a few years ago. He predicts that Wal-Mart's "tipping point" will drive prices lower.

"There are definitely costs. Some labels had to be modified," said Mark Gatehouse, director of replenishment for Wrangler jeans maker VF Corp., adding that while Wal-Mart is subsidizing the costs of the actual sensors, suppliers have had to invest in new equipment. "But we view this as an investment in where things are going. Everyone is watching closely because no one wants to be at a competitive disadvantage, and this could really lift sales."

Wal-Mart won't disclose what it's spending on the effort, but it confirms that it is subsidizing some of the costs for suppliers.

Proponents, meanwhile, have high hopes for expanded use in the future. Beyond more-efficient recalls and loss prevention, RFID tags could get rid of checkout lines.

"We are going to see contactless checkouts with mobile phones or kiosks, and we will see new ways to interact, such as being able to find out whether other sizes and colors are available while trying something on in a dressing room," said Bill Hardgrave, head of the RFID Research Center at the University of Arkansas, which is funded in part by Wal-Mart. "That is where the magic is going to happen. But that's all years away."
